Investigators said at least one shot was fired in the packed parking lot, hitting a 38-year-old man.

KCRA 3 spoke with a friend of the victim.

"He watched me, made sure nobody hurt me. We looked out for each other," said Bianca Martinez.

Police told KCRA 3 the man appears to have been targeted. Investigators are still trying to determine a motive.

"The victim walked up to the vehicle, and right after that, shots were fired out of the vehicle. The suspect's vehicle (then) pulled out of the parking lot and went westbound out of the McDonald's," said Joseph Silva of the Stockton Police Dept.

Police said they found what could be the suspect's car a few blocks away, but no one was inside. Officers have not released a description of the gunman.

According to police, the victim was not an employee of McDonald's or a customer.

Investigators said McDonald's surveillance cameras were rolling when the shooting took place.

Police said the shooting is the 52nd homicide case in Stockton for 2012. It was the 18th to take place during daylight hours this year.
